Abstract

An arrangement for aligning and stacking laminations and for transporting formed stacks of laminations with the laminations being provided with a circular inner and/or outer circumference and having stamped patterns defining a plurality of stampings distributed about the circumference of the laminations at equal centering angles. A stack forming device is provided for receiving laminations fed individually thereto with the stack forming device including at least two stack forming elements mounted so as to be selectively separable. The stack forming elements are disposed one above the other in a longitudinal direction of the stack forming device so as to form upper and lower stack forming elements. The lower stack forming element selectively engages the upper stack forming element, with such element being maintained in a fixed position when the lower stack forming element is displaced to a lowered position. A drive arrangement is provided for rotating only the lower stack forming element through stepwise predetermined increments when the lower stack forming element is in the lowered position with the predetermined increments constituting a whole number multiple of the central angle …
